Familiarity: I've put it through the wringer
I use this for everyday use, carting around my three year old son. I can fits snacks, extra clothes for him, a water bottle, phone, tablet (although there is no sleeve for that, still fits), wipes and various other small things. I can also take this as just my bag if I'm going to work or a day out. A laptop won't fit in here, unless it's small. Overall it's a great bag that I'm really, really happy with and you can't beat the quality of Patagonia!
